Abstract

The arrangement has one inverter, known as the min inverter (14), which operates in the low power region with low solar radiation and another inverter, known as the max inverter (15), which operates in the normal to maximum power region. The min-max operation is automated using a fuzzy controller (11). The arrangement achieves a reduction in power losses from the usual 10 to 20 per cent to approximately 5 per cent.

Description

Die Erfindung betrifft eine Anordnung zur Erhöhung des Wirkungsgrades der Energieerzeugung mittels Solarzellen durch zwei Inverter Min und Max genannt, automatisiert mittels eines Fuszy Controllers.The invention relates to an arrangement for increasing the efficiency of the Energy generation using solar cells called two inverters Min and Max, automated using a fuszy controller.

Eine derartige Anordnung ist nicht bekannt, wohl aber der Master slave Betrieb, der auf zwei oder mehreren Invertern gleicher Leistung basiert.Such an arrangement is not known, but the master slave operation based on based on two or more inverters of the same power.

Aufgabe der vorliegenden Erfindung ist es, den unteren Leistungsbereich, in welchem der für die Gesamtleistung projektierte Inverter - im folgenden Max genannt - mit schlechtem Wirkungsgrad arbeitet, durch einen Inverter - im folgenden Min genannt - zu ergänzen und den Gesamtbetrieb durch einen Fuszy-Controller zu automatisieren.The object of the present invention is the lower power range in which the for the total power projected inverter - called Max below - with bad Efficiency works by adding an inverter - hereinafter called Min - and automate the entire operation with a fuszy controller.

Eine derartige Anordnung wurde den Verlust an Leistung von bisher 10-20% auf ca. 5% senken. In Mitteleuropa mit oft diffuser Sonneneinstrahlung und dehalb weit geringerem als projektierten Ertrag, ist dies eine sehr bedeutsame Leistungssteigerung, insbesondere in kleineren und mittleren Anlagen.Such an arrangement has resulted in the loss of power of 10-20% to date lower approx. 5%. In Central Europe with often diffuse solar radiation and therefore far less than projected yield, this is a very significant performance improvement, especially in small and medium-sized plants.

Die Zeichnung zeigt die Prinzipanordnung. Eine im Ganzen mit 10 bezeichnete Anordnung besteht im wesentlichen aus dem Fuszy-Controller 11, der Frequenzsteuerung 12 sowie dem Filter 13 und der beiden Inverter Min 14 und Max 15.The drawing shows the basic arrangement. An arrangement designated as a whole by 10 essentially consists of the fuszy controller 11 , the frequency control 12 and the filter 13 and the two inverters Min 14 and Max 15 .
